What are the primary materials used in custom orthotics?

Custom orthotics are specifically designed to provide support, promote proper alignment, and reduce discomfort in the feet and lower limbs. The primary materials used in crafting these orthotics often include EVA (ethylene vinyl acetate), polypropylene, and silicone due to their unique properties that cater to foot mechanics.

EVA, commonly used in custom orthotics, is a versatile foam-like material known for its cushioning and shock-absorbing qualities, which helps in alleviating pressure on the feet during everyday activities. Polypropylene is a type of thermoplastic that offers durability and stiffness, providing the structural support necessary for corrective devices. Silicone is often incorporated for its softness, flexibility, and cushioning properties, making it ideal for areas that require added comfort.

These materials are chosen not only for their mechanical properties but also for their capacity to be molded and adjusted to fit an individual's specific foot shape and needs, which is a vital aspect of custom orthotics. This combination of materials helps in achieving a balance of comfort, support, and effectiveness in enhancing overall foot function.
